# Checkbox

> Integrate your application with the Checkbox API

## 🚀 Quickstart

Connect to Checkbox with Nango and see data flow in 2 minutes.

**1. Create the integration**

In Nango ([free signup](https://app.nango.dev)), go to [Integrations](https://app.nango.dev/dev/integrations) -> *Configure New Integration* -> *Checkbox*.

**2. Authorize Checkbox**

Go to [Connections](https://app.nango.dev/dev/connections) -> *Add Test Connection* -> *Authorize*, then select your Checkbox environment (production or sandbox) and enter your Checkbox Partner API key. Later, you'll let your users do the same directly from your app.

**3. Call the Checkbox API**

Let's make your first request to the Checkbox API. Replace the placeholders below with your [Environment API key](https://nango.dev/docs/reference/backend/http-api/api-keys.md), [integration ID](https://app.nango.dev/dev/integrations), and [connection ID](https://app.nango.dev/dev/connections):

**cURL**

```bash theme={null}
curl "https://api.nango.dev/proxy/partner/api/v1/ticketing/boards?limit=50" \
  -H "Authorization: Bearer <NANGO-API-KEY>" \
  -H "Provider-Config-Key: <INTEGRATION-ID>" \
  -H "Connection-Id: <CONNECTION-ID>"
```

**Node**

Install Nango's backend SDK with `npm i @nangohq/node`. Then run:

```typescript theme={null}
import { Nango } from '@nangohq/node';

const nango = new Nango({ apiKey: '<NANGO-API-KEY>' });

const res = await nango.get({
    endpoint: '/partner/api/v1/ticketing/boards',
    params: { limit: '50' },
    providerConfigKey: '<INTEGRATION-ID>',
    connectionId: '<CONNECTION-ID>'
});

console.log(res.data);
```

Or fetch credentials with the [Node SDK](https://nango.dev/docs/reference/backend/backend-sdk/node.md#get-a-connection-with-credentials) or [API](https://nango.dev/docs/reference/backend/http-api/connections/get.md).

✅ You're connected! Check the [Logs](https://app.nango.dev/dev/logs) tab in Nango to inspect requests.

**4. Implement Nango in your app**

Follow our [Auth implementation guide](https://nango.dev/docs/guides/primitives/auth.md) to integrate Nango in your app.

To obtain your own Partner API key, follow the setup guide linked below.

## 📚 Checkbox Integration Guides

Nango maintained guides for common use cases.

* [How to obtain your Checkbox Partner API key](https://nango.dev/docs/api-integrations/checkbox/connect)
  Choose your environment, create a Partner API key in Checkbox, and optionally add your Create Assessment account ID and base URL

Official docs: [Checkbox](https://www.checkbox.ai) (API documentation is provided by Checkbox to partners and customers)

## 🔌 Calling the Create Assessment API

Checkbox has two APIs, and one API key and one Nango connection cover both:

* **Matter Management (Partner API)** is served under `/partner/api/v1/ticketing` from the connection's environment: `https://app.checkbox.ai` for production or `https://sandbox.checkbox-app.com` for sandbox. Nango uses this base URL by default, so no extra setup is needed.
* **Create Assessment** (`POST /restapi/v1/assessments`) is served from the same base URL that Checkbox assigns to each environment. Nango adds the `X-Consumer-Custom-Id` header automatically when the connection's **Account ID** is set.

```typescript theme={null}
const connection = await nango.getConnection('<INTEGRATION-ID>', '<CONNECTION-ID>');

const res = await nango.post({
    baseUrlOverride: connection.connection_config['assessmentsBaseUrl'],
    endpoint: '/restapi/v1/assessments',
    data: {
        appID: 1234,
        teamID: 56,
        assessmentName: 'NDA Review — Acme Corp',
        data: { TXT0: 'Acme Corporation', RAD0: 'High' }
    },
    providerConfigKey: '<INTEGRATION-ID>',
    connectionId: '<CONNECTION-ID>'
});
```

With the HTTP proxy, send the same base URL in the `Base-Url-Override` header.
